GAS-STOVE.

Specification of Letters Patent.

Patented Oct. 26, 1909.

Application filed August 20, 1908. Serial No. 449,550.

To all whom it may concern:

Be it known that I, JACOB I. ORKIN, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Gas-Stoves, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in gas stoves, in which means are provided for, heating a tank of water at the same time that the stove is being used for cooking or other purposes, thereby insuring a constant supply of hot water, as long as the burners are in operation.

The object of the invention is to provide a gas stove of simple construction, provided with a water tank and means for simultaneously supplying heat for general purposes and directly'heating the water tank, and it is also anobject to provide means for facilitating a circulation of water within the water tank.

Another object is to provide improved means for employing direct heat simultaneously for cooking and heating the Water tank, Without any portion of the tank or other structure intervening to deflect the flame and heat, thereby the heat available for cooking' purposes is not reduced and consequently the elliciency of the stove for both cooking and heating purposes is entirely retained.

1 Another object is to provide burners having means for draining the bu'rnerholders of any liquidsthat may fall into the burnerholders during the process of heating or cooking.

Inprevious devices of this kind for utilizingheat'simultaneously for the purpose of cooking and h'eating water, a portion of the water tank or other structure has generally intervened to either deflect or entirely intercept the direct heat from the burners.

The invention consists in the combination of elements and in certain parts of novel construction entailedin the combination of said elements to obtain the desired result.

A full understandingof my invention can bestbe given bya detailed description of a preferred construction embodying the various features of my invention, and such a descri tion will now be iven' in connection with the accompanying rawingsg and I attain my object by the mechanism there illustrated, showing such preferred construction, and the features forming theinvention will then be specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspcctiveof my improvedgas stove, showing the inlet and outlet water pipes. Fig. 2 is a central vertical section of the gas stove. Fig. 3 is a plan view of one of the burners. Fig. 4 is a cross section showing a burner and burner-holder and adjoin ing parts. Fi 5 is a cross section of the outlet-pipe an supplementary valve. Fig. 6 is a. front sectional elevation of the valve seat with the valve removed.

Latitude is allowed herein as to details, as they may be changed or varied at will without departing from the spirit of the invention and the same yet remain intact and be protected.

In the drawings 1 is a water receptacle or tank supported by legs 2, which are attached to the'base-plate 3 of the tank. The tank is provided upon its upper-plate l with gas burner-holders 5, which extend into the tank and are either formed in the upper-plate 4 or attached thereto by any suitable means. Gas burners 6 of the same depth as burnerholders 5 are centrally mounted within the burner-holders 5 and are provided with gas supply-pipes 7 which are connected with a main as supply-pipe 8, attached to the front side of the tank. The gas supply-pipes 7 have lever-cocks for controlling the supply of gas admitted to the burners 6 and the supply-pipe 8 is provided with a threaded portion 10 for connecting with the gas by means of a rubber tube or otherwise. The burners 6 and burner-holders 5 may be made deeper than they are shown in the drawings and may be extended to the bottom of the water tank, if desired, in which case the po sition of the main gas supply-pipe 8, and the gas supply-pipes 7 with their adjacent parts would be changed accordingly.

The gas burners 6 are provided with gas jet holes 11 upon their upper-surfaces 12, each of which, when the gas is lighted, forms a separate gas jet. On the sides 13 of the gas burners 6 are a plurality of gas-jet holes 14, each of which forms a separate gas-jet and serves to direct the as flame against thesides 15 of the gas urner-holders '5, thereby heating the entire surface of the gas burner-holders 5, and, therefore, the entire tank, from which the heat is communicated to the water 16 in the tank, which is shown surrounding the gas burner-holders 5.

Water enters the tank through an inletpipe 17 provided with a cock 18 and any suitable means may be employed to connect the inlet-pipe 17 with the water supply. The inlet-pipe 17 is located in a corner of the upper-plate 4 of the tank and extends down into the tank almost to its base-plate 3. On the opposite side of the tank is an outlet-pipe 19 provided with a faucet-cock 20, throu h which hot water may be drawn, when desired. The outlet-pipe 19 is placed in one of the side-walls of the tank diametrically opposite to the inlet-pipe 17 and extends upward almost to the upper-plate t. A water gage 21, provided with pipes 22 which enter the tank, is placed on one side of the tank and serves to indicate at all times the height of the water in the tank. Cooking plates 23 on the burner-holders 5 serve to support any article placed above the burners 6. A vent-hole 24, provided with means for opening and closing the same, is located in one corner of the upperplate 4 and is shown open in the drawings, which is necessary when the inlet-pipe cock 18 is closed, so that any steam in the tank will have a means of escape. The burners 6 are provided with a plurality of draininggrooves 26 on the under-side, for the pur pose of drawing off any water or other liquid that may drop into the burner-holders 5. A drain-pipe 25, which surrounds but is not in contact with the gas supply-pipe 7, enters and connects the burner-holders 5 with the side-wall of the tank, and serves as an outlet for water-or other liquid coming from the burner-holders 5. The drain-pipe 25 has a lip 27 at its extremity to facilitate the passage of water or other liquid from the pipe 25. The draining rooves 26 serve to direct the flow, from al parts of the bottom of the burner-holders of any liquid falling therein, outward and towardjthe drain-pipe 25, and also aid in preventing clogging from this source of the gas burners. The outlet-pipe 19 is provided at its base, adjoining the base-plate 3 of the tank, with an extended portion 32, which has a Valve, so that the same may be opened when the water used is without pressure. In case the inlet-pipe 17 is not connected to a water su ply under pressure the vent-hole 24 is lett open in order to revent an explosion by excess steam caused in heating the water, and as the water is drawn from the tank ordinarily near the top through the upper portion of pipe 19, it is necessary to provlde the extended portion 32 with .a valve, so as to draw the water when the level of the water is below the opening in the top of the pipe 19.

The valve has a cross-piece 28, which is located in the extended ortion 32 of pipe 19, between an opening 1 in the extended portion 32 and pipe 19. The opening 31 permits the water to pass from the water tank into the extended portion 32, through the valve and hence through the faucet-cock 20. Adjoining the cross-piece 28 is a valveseat 30, which is provided with a central, tapered opening. The cross-piece 28 is provided with a central, threaded hole, through which passes the threaded-rod of the lockingscrew 29, the head of which is tapered on its under-side, to fit the tapered opening in the valve-seat 30. The head of the locking-screw 29 is slotted on its upper-side, so as to provide means for opening and closing the valve, by using a screw driver or other suitable tool. In Fig. 5 the valve is shown opened, as is the case when the water supply is not under pressure.

In Fig. 1 the water in the tank is shown partly Withdrawn, and the vent-hole 24 is shown open and the inletpipe cook 18 closed. The outlet-pipe 20 may, if desired, be a straight pipe located near the base-plate 3 of the tank.

In operation the tank is filled with water and the burners 6 lighted. The gas burners at the same time that they are being used for cooking or other purposes heat the sides 15 of the urner-holders 5, thereby heating the burner-holders 5, from which the heat is conveyed to the entire tank, and hence to the water in the tank.

By placing the inlet-pi e 17 and the outlet-pipe 19 in diametrical y o posite corners of the tank the circulation of ot water within the tank is facilitated, when the inlet-pi e cock 18 is opened to admit cold water to t e tank and the faucet-cock 20 is at the same time opened to draw hot water.

It is to be understood that my invention is not limited to the specific details of construction shown in the accompanying drawings, but that the said details may be varied in the practical carrying out of my invention. It is also to be understood that the combinations specifically set forth in the several claims are intended to be separately claimed without limitation to the use in connection therewith of other features and details of construction illustrated.
